New Functionality in Mastercam 2021

Mastercam 2021 new

What’s new in Mastercam 2021 ?

Dear Friends,

Today in this post I would like to share the new functionality come up on Mastercam 2021 version. This version was released globally for public testing on 10th February 2020 via Beta Program for Mastercam 2021. Shops all over the world, from small job shops to Fortune 100, get a chance to test-drive Mastercam 2021 before it is released and provide valuable feedback to help shape the final product. Participants in the Beta Program get an early look at dozens of powerful new tools for simple to complex jobs.

Faster, more flexible multiaxis programming. As more shops continue to rely on streamlined multiaxis cutting for single-setup precision, Mastercam 2021 adds new techniques and strategies such as Expanded Multiaxis Pocketing, a new 3+2 Automatic Roughing toolpath, enhancements to the 5-axis Flowline toolpaths, and more.

1. Machining Chamfer Holes Based on Width or Depth

Mastercam 2021 features a new toolpath, Chamfer Drill. Using tools with a tip angle, the Chamfer Drill toolpath chamfers holes after calculating the correct depth based on the desired width or depth. The Chamfer Drill toolpath also lets you select holes of different diameters or sizes—or that lie in different planes—and machine them in a single operation with a single tool.

You can use any tool with a tapered tip, not just a drill. Like other drill operations, you can use the Tool Axis Control page to choose 3-4-, or 5-axis output. Choosing 4-axis or 5-axis output gives you access to additional multiaxis features, like Safety Zone. To create the toolpath, select Chamfer Drill in the Hole making section of the 2D Mill toolpaths. Then, in the graphics window, select the entities you want to add to the Features list. Use the following methods to make and manipulate your selections:

  • Select entities to add or delete them from the Features list.
  • Click or use window selection to choose solid holes, solid arc edges, wireframe arcs, lines, points, or AutoCursor positions.
  • [Ctrl+Click] to select all matching radius solid features.
  • [Ctrl+Shift+Click] to select all matching radius solid features on the same vector as the initial selection.
  • Click a selected solid feature’s arrow to change direction.

2. Machining with a Customizable Multi-Segment Drill Cycle

Mastercam 2021 features a new toolpath, Advanced Drill.

Advanced Drill is a customizable multi-segment drill cycle that is useful for spot drilling, deep hole drilling, and back spot facing. Each segment of the drill cycle can be defined in a table on the toolpath’s Cut Parameters page.

For each segment, you can customize any or all of the following conditions:

  • Define individual pecks within the segment, including retracts to simulate a chip break cycle.
  • Set the feed rate or choose rapid motion.
  • Change the spindle speed and direction.
  • Turn coolant options on or off.
  • Add manual entry comments or code.
  • Fine-tune the order in which the commands are output.

Like other drill operations, you can use the Tool Axis Control page to choose 3-4-, or 5-axis output. Choosing 4-axis or 5-axis output gives you access to additional multiaxis features, like Safety Zone.

3. Machining with The New 3+2 Automatic Roughing Toolpath

The new 3+2 Automatic Roughing toolpath automatically makes multiplane 3-axis toolpaths for roughing. Mastercam analyzes the model and stock, and then creates a roughing toolpath. Then Mastercam calculates the remaining stock and computes a new toolpath. This continues until only a defined amount of stock remains. The results are all contained within the one toolpath.

The image below shows the new toolpath on a part with Section view enabled, allowing you to better see the toolpath.

4. Machining Custom Thread Forms

Mastercam 2021 introduces the new Lathe Custom Thread toolpath to support custom thread forms.

The new toolpath also takes advantage of Mastercam’s next-generation panel interface to simplify and streamline your programming workflow. You can select chained geometry to represent the thread cross-section or select one of four parametric definitions:

  • Rope
  • Buttress
  • Square
  • Trapezoidal

Parametric definitions let you define the profile by entering dimensions directly in a properties grid, eliminating the need to chain geometry.

Mastercam lets you define roughing and finishing passes with separate cutting parameters.

The new custom thread module also supports Mastercam’s other advanced threading and toolpath features, such as multi-start threads, tool inspection, ID/OD threads, allowances for mating parts, and cross-centerline turning. You can even name and save custom thread forms so you can easily retrieve and reuse them in future operations.
